Bringing PyQGIS and PyQt into already settled Anaconda Python environment in PyCharm

Question

I have Anaconda Python environment with different packages required for developing a QGIS plugin (including the Plugin Builder Tool etc.).

(qgsdata) C:\TempDaten\_dev\QgsData>conda info

     active environment : qgsdata
    active env location : C:\TempDaten\Programme\Anaconda3\envs\qgsdata
            shell level : 1
       user config file : C:\Users\taras\.condarc

                          C:\Users\taras\AppData\Local\conda\conda\envs
               platform : win-64
             user-agent : conda/4.12.0 requests/2.24.0 CPython/3.8.5 Windows/10 Windows/10.0.19041
          administrator : False
             netrc file : None
           offline mode : False

How can I extend it with PyQGIS and PyQt?

My technical propriety:

• Window 10 Enterprise Version 1909
• PyCharm 2020.3.3 (Community edition) in C:/TempDaten/Programme/PyCharm Community Edition 2020.3.3
• QGIS 3.22.5-Białowieża in C:/Program Files/QGIS 3.22.5
• Anaconda3 2020.11 in C:/TempDaten/Programme/Anaconda3

I tried approaches offered in these articles:

• Access QGIS API from Anaconda python environment using Conda-Forge
• Using PyQGIS in PyCharm 2020
• Why does QGIS 3.2 "native:extractvertices" algorithm not work properly in standalone script?
• Alexandre Neto | Using QGIS from Conda
• Spatial Galaxy | Quick Guide to Getting Started with PyQGIS 3 on Windows
• YouTube | QGIS Python Setting up PyCharm for QGIS Development (for QGIS 2.x)

But nothing useful. I can not understand how to bring and merge together already existing Python environment in Anaconda with PyQGIS and PyQt.

I could run the created 'pycharm_qgis.bat' file with the following settings:

@echo off 
@ECHO OFF 

set OSGEO4W_ROOT=C:\Program Files\QGIS 3.22.5

@echo off
call "%OSGEO4W_ROOT%\bin\o4w_env.bat"
call "%OSGEO4W_ROOT%\bin\qt5_env.bat"
call "%OSGEO4W_ROOT%\bin\py3_env.bat"

@echo off
path %OSGEO4W_ROOT%\apps\qgis-ltr\bin;%PATH%

set GDAL_FILENAME_IS_UTF8=YES

set VSI_CACHE=TRUE
set VSI_CACHE_SIZE=1000000

set QGISNAME=qgis

set QT_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\qgis-ltr\qtplugins;%OSGEO4W_ROOT%\apps\qt5\plugins

set PYCHARM="C:\TempDaten\Programme\PyCharm Community Edition 2020.3.3\bin\pycharm64.exe"

set PYTHONPATH=%OSGEO4W_ROOT%\apps\qgis-ltr\python
set PYTHONHOME=%OSGEO4W_ROOT%\apps\Python39
set PYTHONPATH=%OSGEO4W_ROOT%\apps\Python39\lib\site-packages;%PYTHONPATH%

set QT_QPA_PLATFORM_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\Qt5\plugins\platforms
set QGIS_PREFIX_PATH=%OSGEO4W_ROOT%\apps\qgis-ltr

start "PyCharm aware of QGIS" /B %PYCHARM% %*

and see the QGIS Python Interpreter in PyCharm:

A simple command from qgis.core import * works.
